5.4.6 Set LUN Mapping
On this screen, add/change/delete mapping information for the Logical Unit Number (LUN) rec-
ognized by hosts, and the Logical Volume number used in the ETERNUS DX400/DX8000 series,
without stopping operations. Relying on the mapping between the two types of numbers, hosts
can access the Logical Volumes in the
ETERNUS DX400/DX8000 series.
Set LUN Mapping only when hosts and the ETERNUS DX400/DX8000 series are connected via
FC-CA or iSCSI-CA.
• Make sure to stop host acces s t o t h e F C - C A P o r t o r i S C S I - C A P o r t

When adding a new LUN Mapping, it is not necessary to stop host
access.
• When copying LUN Mapping information to an active FC-CA or iSCSI-
CA, make sure to stop host access to the copy destination FC-CA or
iSCSI-CA port. When copying LUN Mapping information to a newly
added FC-CA or iSCSI-CA, it is not necessary to stop host access.
• [Set LUN Mapping] is available when the [Affinity Mode] of the target
FC-CA Port or iSCSI-CA Port is [OFF (Disabled)].
• Mapping to a "Work Volume" during RAID Migration is not allowed.
The operating status (Work Volume information) of Migration can be
checked by the [Progress of RAID Migration] function. "Work Volume" is
a temporary volume created for Migration operation.
• Mapping to a Snap Data Pool Volume is not allowed.
